At the start of their second year of high school, underachiever Su Nian unexpectedly becomes the deskmate of the aloof top student Gu Yanzhi. He acts cold, but quietly tutors her, organizes her mistakes, and draws smiley faces on her scratch paper. Starting with a physics test she scored 38 points on, she turns her life around and grows under his protection, discovering the warmth beneath his icy exterior. From secretly loving each other to bravely confessing their feelings, they weather ten years of trials, from the college entrance exam and living apart to starting a business and family opposition. In the end, they go from school uniforms to wedding gowns. Su Nian becomes a renowned comic artist, and Gu Yanzhi becomes a university professor. Time proves that the best love is one where two people help each other become their best selves. What is cherished is never forgotten, and love will be answered in time.
